Year 9 - HEAT TRANSFER

Big Question - Can Heat Knowledge Save the World?

In Malaysia we try to keep cool and stop heat entering our buildings. We waste energy resources cooling it.In cold climates, in the winter, the battle is to keep heat in a building and stop energy escaping. When it does escape energy resources are used to heat it.

Your Task:

Play the the attached PowerPoint on Heat Loss and Insulation BUT REMEMBER - whatever stops heat leaving a building will also stop it entering here!Think about measures you could take in your home to keep it cooler without air con.

What you will be doing in the lessons:

You will be working independently in your groups to study this topic.You will use a copy of the sheet below to keep track of your progress during the 3 lessons when you are experimenting and researching.

What each group needs to do:

Make a Tackk linking all of the following things together sorted by heat transfer method

An explanation of each process

Examples of where the process can be found / is useful

A copy of each process Question sheet completed and marked

A Copy of each Process Mini Quiz / Test corrected

A video summary of the experiments you did

The Roles you need to share out:

Resources Manager - ensure all information is completed and available for the Tackk

Tackk Producer - overall co-ordinator and support for resource manager in early weeks

Video Producer - record video and photos as appropriate and document support in lessons

You will all need to work together in class and liaise when you are at home, to make sure the content and question answers are of the best standard your group can manage and that the Producers have everything they need to do their job.

Week Plan:

Week 1 - Introduction, allocate roles and start experiments.

Week 2 - Lab out of use (GCSE Practical Exam) - work in groups to compile the background theory, explanations and examples, answer the question sheets.

Week 3 - Main chance to complete experiments, do Mini Tests and Quizzes if you get a chance.

Conduction can happen in gases, but it is very slow - heat is usually transferred by one of the other methods UNLESS the gas is trapped. (See the animation below to view the mechanism, but it must be on a laptop)

Try to view these PowerPoint links on a pc - the layers within some of the slides will not work on ipad or Mac.

This resource will be updated with links and information you may find useful in the lessons or for homework, to improve your knowledge and understanding.Inform me if there are any additional resources you would like me to include
